What type of gas options are there? All Octane levels, Ethanol free? I actually go out of my way to find the latter.
Mid-grade (89) is just a mix of the two - it shouldn't be hard to implement.
That's the perception (and they are happy for you to think that), but I don't believe it's actually true.
And in any case, if it is true, a mix would simply have a lower level of additives for midgrade and that seems right to me.
> although there are older gas stations and cheaper stations which mix high and low on-site at the pump for medium.
I'm almost 100% certain that almost all gas stations have just two storage tanks and the pump mixes them.
